SPECIFICATION forming part of Letters Patent N o. 792,516, dated June18, 1905.

Application filed August 25, 1904. Serial No. 222,155.

To all 107mm, 211 may concern.:

Be it known that we, SAMUEL M. HANLoN and VILLIAM L. HANLoN, citizens ofthe United States, residing' at Sterling, in the county of Rice andState of Kansas, have invented certain new and useful Improvements inSeparators; and we do declare the followingto be afull, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in separators.

The object of the invention is to provide an air-blast straw-rack forseparators, whereby the grain will be thoroughly separated from thestraw and chaff.

A further object is to provide means whereby a blast of air may bedirected against the straw at different points, and thus loosen up allstraw and chaii' that passes over the strawrack.

Vith these and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be more fully described, and particularly pointed out in theappended claims.

ln the accompanying' drawings, Figure 1 is a vertical longitudinalsectional view through a `separator and showing the application of theinvention. Fig'. 2 is a vertical cross-sectional view on the line 2 2 ofFig. 1, and Fig. 3 is a side view of the air-blast fan.

Referring more particularly to the drawings, 1 denotes the frame orcasing of a threshing-machine or separator, which may be of the usual orany suitable construction. Vithin said frame or casing, at the forwardend of the same, is arranged the usual threshing-cylinder 2 and concave3, to which the straw and g'rain are fed from the feed-table 4Z. Fromthe concave 3 extends the grate 5, over which the straw is forced by thebeater 6 after leaving the concave.

Arranged beneath the end of the grate 5 and extending upwardly andrearwardly from the same is an endless slatted conveyer or straw-rack 7,upon which the straw falls after leaving' said grate and by which it isconducted to the air-blast straw-rack 8. The straw-rack 8 consists of aninclined frame having tapering side boards 9, which are pivotallyconnected to the sides of the separator-easing in any convenient manner.Between said side boards and at the upper edges of the same is arrangeda grating 10, formed of a series of slats or strips spaced apart andarranged on a slight angle, so that theedges of the same overlap, asshown. At the rear end of the side boards 9 is arranged an inclined endboard 11, which closes this end of the straw-rack frame. The straw-rack8 is also provided with an inclined return-bottom 8, which catches thegrain passing through the rack 8 and discharges the same fromits lowerend onto the grain-bottom 15. Above the grating 10 is arranged a seriesof longitudinally-disposed stripsor bars 12, forming the upper side ofthe rack. There may be any desired number of the bars 12, five beingfound to be the most effective, the rear ends of the same being adaptedto project rearwardly beyond the side pieces of the rackframe and thegrating' 10, so that the grain and chaff which may have remained in thestraw when the same reaches this point will fall through before thestraw leaves the rack. The upper edges of the bars or strips 12 arenotched in a zigzag' manner, as shown, to facilitate the movement of thestraw across the same.

Below the rear projecting ends of the strips 12 and extending' to therear end of the machine is a second upwardly-inclined strawrack 13 andonto which the straw from said rack 8 falls. The straw then passesacross this rack and is discharged at the rear end of the same, whileany grain and chaff left therein falls through onto a downwardly-inclined upper return-bottom 14, by which it is conveyed forwardly anddownwardly and dropped onto the slatted end of a grain-bottom 15, fromwhich it falls, together with the rest of the grain caught by saidbottom, onto a lower inclined return-bottom 16, by which it is conductedto a spiral or other form of conveyer 17, and thereby carried anddeposited into bags or other suitable receptacles.

At the lower forward end of the straw-rack IOO 8 is arranged afan-casing 18, which opens into the frame ot' the rack 8 below thegrating 10. To the upper and lower edges of the fan-casing opening arehinged air-deflecting plates or wind-boards 19, which may be adjusted tovarious angles to direct the air-blast from the fan to any portion ofthe straw-rack that may be desired. The plates or boards may be adjustedin any suitable manner, but are preferably adjusted by extending thehinge or pivot pins oi' the same through the sides of theseparator-casing and providing them with suitable handles.

Vithin the easing 18 is mounted an airblast Afan 20, which may be drivenin any suitable manner to create a strong blast of air which passesthrough the straw-rack and straw and blows the chatl and lighterparticles ot' straw and dirt out. This airblast also cleans the grainfrom the chatl1 as it Jfalls through the grating 10 onto the bottombelow.

At the upper rear end of the frame 8 is arranged an air-deflecting plateor wind-board 21, which is also hinged similarly to the windboards 19 topermit the same to be adjusted to regulate the course of the air at therear end of the straw-rack. lVhen in its lowered position, the free endof the wind-board Q1 lies adjacent to but does not engage the end board11, thereby forming a space or opening through which any grain may passthat has been blown through againstthe board 11 by the Ytan 20. On theends of the Afan-casing 18 are slidably mounted plates 23, which areadapted to be moved over the inlet-opening 24 in said ends to vary thesize or' the same, and thereby regulate the supply of air taken in bythe fan and consequently control the amount of air discharged from thesame onto the straw-rack.

The straw-racks and grain-bottoms of the separator may be oscillated orshaken in any suitable manner to force the straw and grain over thesame.

To the fan-casing 18, adjacent to and immediately below the pivotedconnection of the air-deilecting plates 19, is connected the upper edgeof a stationary blast-retard board 25, the lower end of which liesthree-fourths ot an inch above the inclined return-bottom 8 of theair-blast straw-rack 8.

By the arrangement of the straw-racks and the forming oli adjustablewind or air-deflecting boards, as herein described, the grain will bethoroughly separated Afrom the straw and cleaned from all chaiil andforeign mattei'.

From the foregoing description, taken in connection with theaccompanying' drawings, the construction and operation of the inventionwill be readily understood without re quiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction maybe resorted to without departing from the prineiple orsacrilicing any of the advantages of'- this invention.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. In combination with a threshingmechanism and a conveyer for thethreshed grain, a rack on which the threshed grain is discharged andhaving openings for the passage oi: grain tlierethrough, a douuiwardlyand forwardly inclined end board depending from the rear end of saidrack, a similarly-inclined returnbottom under the said rack andterminating short of the said end board, to 'form a dis charge-openingbetween them, a casing having a diseharge-opening in one side betweenthe front ends oi' the said rack and return-bottom, a blast-fan in saidcasing, and pivoted del'lcctors at the upper and lower sides of saidopening, to be turned in position to close the same, open said openingto any desired extent, and to direct the blast Yfrom the Ylian upwardlyand rearwardlyunder and to any portion oi'l the rack, substantially asdescribed.

2. 1n combination with a threshing mechanism and a conveyer for thethreshed grain` a rack on which the threshed grain is discharged andhaving openings for the passage of grain therethrough, a downwardly andforwardly inclined end board depending from the rear end of said rack, asimilarly-inclined returnbottom under the said rack and terminatingshort of the said end board, to Jform a diseharge-opening between them,a 1etai .l-board spaced from and above the lower end of thereturn-bottom, and means to discharge a blast et' air rearwardly overthe retard-board and through the space between the rack and bottoni,substantially as described.

In testimony whereotl wehave hereunto set our hands in presence of twosubscribing witnesses.
